Walnut - Juglans nigra

Walnut heartwood is a rich dark brown to purplish-black, mostly straight grained, but with wavy or curly grain occasionally present. The texture is rather coarse. Walnut works with hand or machine tools without difficulty, but with a moderate blunting effect on cutting edges. Holds nails or screws well, glues satisfactorily, and polishes to a high finish.
